Heat strip installation

relay board bad.

Who installed new unit? Is this a ducted system? Why was it replaced, what was wrong with old unit?

Sounds like it's low on refrigerant, if you haven't used it for a while they normally leak at the compressor shaft seal

You can get the heat strip at your local heating air distributer try looking for cc dickson company you will need the model number and serial number

I see what you see also in the manual. The difference is the Heat Strip package that part is optional and the 600212-001 with the optional heat strips becomes the new 600315-001 I talked to Dometic Duo-Therm and the models are the same but they both are not heat pumps but the new heat strip package comes on when told to go into heat mode when you change the thermostat to heat. The part you purchased will fit both model numbers you listed for your roof top air conditioner. Thanks, Sea Breeze

Shouldn't be a problem.

Your choices are another Dometic or a Coleman
I prefer the Coleman But the amount of extra cooling you will get by stepping up to a 15K unit will probability not be worth the added cost

Hi, like most of the RV roof tops, they will have a manual showing the type and wattage of heat strips you're system calls for. It comes as a unit, pre-wired to fit and set in place. You should have no problems installing a heat strip kit, but make sure you get the right one that the unit calls for as they do make several models. Very self explanatory. Also, be sure that you're system calls for a heat strip package?? Good Luck, and if you need more help please contact me. Very easy to set in place and plug in. Sincerely,

I have a dometic 13500 BTU Roof mount a/c. It is set up with the duo-therm analog thermostat. The system cools fine. The problem is that the a/c gets down to the right temp, then it turns off like it should but turns right back on within a few seconds. Any help would be greatly appreciated.
